During our static electricity unit, for me the three most important things I learnt about static electricity are:

 

-The different laws of static charge, how objects with the same charge repel from each other, objects with like charges attract to each other and charged objects are attracted to neutral objects.  I think this is important because we have to understand what happens when different charges react.

 

-The difference between charging by conduction and charging by induction. Conduction is when you charge a neutral object by touching it to a charged object, an example of induction is when you put a negative charge near the sphere of an electroscope, the leaves will repel. This is important because it is interesting to learn the different ways you can charge objects and trying these ways on electroscopes.

 

-How charges move through different materials, materials where it is easy for electrons to travel through are objects such as metals these are known as conductors. Materials where its hard for electrons to move through consist of stuff like rubber, wool, plastic these are known as insulators. This is important because we need to know what things electricity can travel through easily and things it is harder to travel through.

 

The lab that I found post helpful in learning about static electricity was the static electricity lab where we used a balloon and static and “John Travoltage” simulators. I enjoyed this lab because it gave you a good visual of what actually happens when you test different reactions to electric charges.
